Yui is a beautiful, shapely married woman working part-time, but lately she has seemed listless. She admits that her husband no longer has sex with her, so her coworker offers to relieve her tension with a shoulder massage. Seeing her seductive body up close, he begins fondling her breasts—and she does not resist. He undresses her, squeezes and sucks her tits, and soon her pent-up desire spills out in helpless moans. Now he intends to give this neglected wife the release she has been craving.
